Level 7. Hara-Kiri Harbor

Start inside a room and automatically receive the Riot Gun. Pick up the available ammo.

Head out the door, take a right, pick up the Uzi, and enter the corridor.

Continue until you see large crates. Grab the grenade shells and Uzi clips located behind the crates.

Proceed into the harbor and locate a boat with explosive barrels. Destroy the barrels to eliminate enemies inside.

Retrieve the RED KEY from the boat.

Go to the red key door, which is situated directly behind the house where you started, and use the RED KEY to open it.

Enter the red key door and defeat the female ninjas that attack you.

Collect the nuke and the SILVER KEY.

Exit the red key door, turn right, then left. You will see the silver keyhole.

Place the SILVER KEY in the keyhole to gain access to the silver key door.

Enter the silver key door and defeat all the brown ninjas, a ripper, and a coolie. Stock up on any needed items and grab the repair kit.

Return outside to the open water.

Locate a steamed waterboat (you only need one). Use the repair kit you found at the silver key house on the broken vehicle.

Drive the repaired vehicle until you find a small waterfall with an opening at the top. Drive over it and jump up to find shotgun shells and the BRONZE KEY.

Go to the Bronze Key door, located directly across from the silver key door, and use the BRONZE KEY to open it.

Enter the Marketplace. Lo Wang will comment about a woman being his old girlfriend.

In the Marketplace room, find a switch. Activate the switch, dive into the water, swim through the opening, grab the key, and swim back before the passage closes. It is recommended to save your game before attempting this due to potential interference from Koi fish.

Once you exit the Marketplace room, take the path to the left of the silver keyhole.

Stay on the right wall as you move forward. Turn right, then left to find the gold key door.

Use the GOLD KEY on the door and enter.

Defeat the baby rippers and pick up the caltrops and missile launcher.

Hit the end level switch to complete the level.
